Such an arrangement permits thebuilding of a very large cloth roll without interference with thevarious loom parts while saving space in the mill to accommodatepersonnel and auxiliary equipment.

BACKGROUND OF THE INVENTION Loom cloth roll take ups have been proposedwherein surface driven take up rolls are carried on the top of the loomand mounted on the loom frame. Such structure is shown in British Pat.No. 1,018,409, published Jan. 28, 1966 and similar structure is shown inUS. Pat. Nos. 2,811,176, 3,502,115 and 3,677,305. The prior art alsocontemplates a winding mechanism comprising a pair of spaced horizontaltransverse frictional take up rolls which are suitably driven andmounted forwardly of the loom, such as illustrated in US. Pat. No.3,433,430, but space requirements are increased thereby. It hasheretofore proved to be impractical however in practice to positionfrictional take up rolls over the loom for building very large rollswhile conserving space within the millv It has been found thatexceptional vibration is imparted from the loom frames to the take upmechanism carried thereby. Moreover, in the case of very large rolls itis necessary that the take up mechanism be cantilevered outwardly behindthe loom to avoid interference of the cloth with the loom beam.

It is important to overcome the vibration problem and provide apractical structural arrangement for supporting the take up equipmentplus the very large cloth roll while avoiding obstructing the workingmechanism of the loom. It is also important to provide effectivemechanisms for exerting control over the cloth for building a tight verylarge cloth roll while disposed out of the way of the loom parts, aswell as personnel and auxiliary roll doffing equipment such as lifttrucks, etc.

SUMMARY OF THE INVENTION It has been found that by positioning spacedvertical frame members, each including a pair of longitudinal standards,outboard of the frame members of the loom, it is possible to avoidexcessive vibration and provide sufficient support to carry the requiredload in a position to avoid interference by the cloth with the loombeam. Since the frame members are constructed of spaced standards,reasonable access may be had for operating and maintaining the variousconventional loom parts with which the device is used. It has furtherbeen found that a take up mechanism having a pair of driven spacedhorizontal transverse frictional take up rolls with means for guidingthe cloth thereto, including a transverse roll carried in horizontalalignment with an adjacent take up roll, affords effective control uponthe cloth by maintaining a predetermined wrap of the cloth about theadjacent take up roll.

An imperforate dirt shield is carried by the loom in superposed relationto a rim of cloth passing beneath the loom. The driving means preferablyincludes a reversible motor driving one of the take up rolls at a firstspeed, a driving connection between the rolls causing the one roll toimpart rotation at a slightly different second speed to the other rollfor building a tight cloth roll, and means releasing such drivingconnection when the motor is reversed to permit an even take off ofcloth avoiding any tendency to pucker By positioning the vertical framemembers outboard of the loom frame members a sufficiently ruggedstructure can be afforded to carry the various drive mechanisms for thefrictional rolls above the loom while isolating the drive and take upmechanism from the oscillations and vibrations during weaving.Horizontal alignment of the peripheries of the transverse roll and takeup roll facilitates a manual placement of a full cloth roll thereonmaking it more accessable to the tines of a lift truck for doffing.

BRIEF DESCRIPTION OF THE DRAWING The construction designed to carry outthe invention will be hereinafter described, together with otherfeatures thereof.

The invention will be more readily understood from a reading of thefollowing specification and by reference to the accompanying drawing.forming a part thereof, wherein an example of the invention is shown andwherein:

FIG. 1 is a perspective view illustrating loom equipment with a clothroll take up constructed in accordance with the present inventionincluding the drive mechanism and control devices for handling thecloth,

FIG. 2 is a longitudinal sectional elevation taken on the line 22 inFIG. 1 further illustrating the support structure and frictional rolls,and

FIG. 3 is a side elevation looking toward theright hand side of FIG. 1showing a take up drive.

DESCRIPTION OF A PREFERRED EMBODIMENT The drawing illustrates a clothroll take up for a loom having a loom beam adjacent the rear of the loomand a cloth delivery roll mounted to receive woven cloth carried betweenthe loom side frame members adjacent the front of the loom. The take uphas means for guiding the cloth from the delivery roll and thencebeneath toward the rear of the loom.

A pair of transversly spaced vertical frame members A, each including apair of longitudinally spaced standards, are carried outboard of theloom frame members adjacent the rear of the loom. A mounting platform Bis carried adjacent the top of the frame members. A pair of spacedhorizontal transverse friction take up rolls C are carried for rotationby a pair of spaced roll supports D. The roll supports are carried bythe platform in transverse alignment therewith for supporting the pairof take up rolls for rotation above and in substantial verticalalignment with the loom beam. Means E for driving the pair of take uprolls are carried by the platform. Means F are provided for guiding thecloth from beneath the loom substantially vertically behind the loombeam to the take up rolls. Preferably, the means F for guiding the clothfrom beneath the loom includes a transverse roll carried in horizontalalignment with an adjacent take up roll C for affording a predeterminedwrap of the cloth thereabout.

A loom of standard construction is broadly designated at 10 and includesa pair of side frame members 11 and 12 bridged by the usual breast beam13. A loom warp beam 14 is carried adjacent the rear of the framemembers 11 and 12 and supplies warp yarn 15 over the usual whip roll 16.The warp yarn 15 forms a shed 16a for making the cloth 17 which isillustrated as passing over the breast beam 13 to the usual delivery ortake up sand roll 18. At this point the procedure varies from theconventional and the cloth is carried over a press roll 19 and thencedownwardly around a pair of guide rolls l and 21 beneath the loompreparatory to its being guided by the mechanism hereof and wound into avery large cloth roll.

A pair of transversely spaced vertical frame members A, each including apair of longitudinally spaced standards 22 are braced at the bottom bycross frame members 23 and at the top by the various components of themounting platform B which bridge the respective standards 22 and extendstransversely between the respective vertical frame members A.

The platform B on the left hand side of FIG. 1 includes spacedhorizontal transverse members 24 which are bridged by a suitablelongitudinal frame member 25. The frame A on the right hand side of FIG.1 is bridged by a longitudinal member 26. The platform further includesa transverse frame member 27 which bridges the longitudinal framemembers 25 and 26 to provide rigidity to the platform structure as wellas the frame members which support it. Suitable angularly disposed framemembers 28 may be employed as desired to add rigidity to the aforesaidframe and platform structure. An additional transverse member 29 (FIG.2) spans the vertical frame members and carries a pair of spacedstandards 30 for limiting transverse movement of the cloth roll upon thefrictional take up rolls C. The transverse frame member 29 is secured tothe frame and platform members through a pair of spaced roll supports D.

The means E for driving the pair of take up rolls C are carried by theplatform and contained within a suitable housing 31. The means Eincludes a motor 32 which through a gear box 33 drives a chain 34 forimparting rotation to the frictional take up rolls C through a sprocket35. The sprocket 35 is carried by the forward roll 36 of the rolls C.The back roll 37 is driven through a sprocket 38 which in turn is driventhrough an endless chain 39 driven by the sprocket 40 carried by theopposite end of the roll 36.

A means F for guiding the cloth beneath the loom includes a guide roll41 carried by extensions 42 of the frame members 11 and 12 and ispositioned to guide the cloth upwardly substantially vertically behindthe loom beam to a cooperating transverse roll 43 which controls thewrap of the cloth l7 and the adjacent frictional roll 37. Thus, thetension exerted upon the cloth 17 as it is wound about a suitable core44 to form a cloth roll 17a, is continuously built upon the frictionalrolls C to a very large size An imperforate dirt shield 17b is carriedby brackets 170 by the loom side frame members just above the run ofcloth passing beneath the loom. The motor 32 is preferably a reversiblemotor for backing cloth off the cloth roll producing slack in thevertical run of cloth past the loom beam. Thus, access may be had aswhen a warp end comes down. It has been found desirable, in order to geta tight wrap on cloth on the cloth roll, to drive one of the take uprolls at a slightly faster speed than the other. In the embodimentillustrated the take up roll 36 is driven faster, having one less tooththan take up roll 37. As noted in FIG. 3 a ratchet wheel 45 is keyed tothe shaft carrying roll 37 as at 450. A spring biased pawl 46 is pivotedas at 46a upon the sprocket. During reversing the pawl will be out ofengagement with the ratchet so that the rolls 37 and 36 will be drivenat the same speed as has been found necessary to avoid placing a puckerin the cloth roll on reversing.
